Procedure

2.4 g of ethyl 2-[2-amino-4-(isoindoline-2-carbonyl)quinazolin-6-yl]-2-methylpropanoate are dissolved in 40 ml of tetrahydrofuran, and 25 ml of 2N sodium hydroxide solution are added. The mixture is stirred at 50° C. for 4 h and subsequently evaporated in vacuo. The mixture is then adjusted to pH2 using 7 ml of 25% hydrochloric acid with ice-cooling, with yellow crystals precipitating. The precipitate obtained is filtered off and dried in vacuo. Yield: 2.0 g (90%) of 2-[2-amino-4-(isoindoline-2-carbonyl)quinazolin-6-yl]-2-methylpropanoic acid;
